As you may have seen while perusing these forums, there are still a number of issues with the installation process of the authoring tool, especially for our non-technical audience. We hoped (and still do) that using vagrant would help to alleviate a lot of these problems, but we're still a way away from where we want to be. Although we're aware of the problems, our development priorities are firmly elsewhere for the immediate future, and so these issues are unlikely to be resolved any time soon.
This post therefore is a call for help to any developers familiar working with, and configuring cross-platform vagrant environments -- we need you! Any help we can get testing, diagnosing and fixing our vagrant set-up would be very much appreciated by not just the core team, but the community as a whole.
